Use when running an email newsletter as a recurring publication — subject + preview pair, issues that turn opens into clicks, the welcome sequence, cadence and engagement tiering, growth loops, and a post-Apple-MPP click scorecard. NOT one-off launch or nurture sends (that is `marketing`), NOT SPF/DKIM/DMARC (that is `email-deliverability`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# newsletter Run the newsletter as a **product you ship on a cadence**, not a one-off send. The job is the system around the recurring issue: the subject + preview that earns the open, the issue body that earns the click, the welcome sequence that activates a new subscriber, the cadence and segmentation that keep the list healthy, the growth loops that compound it, and a scorecard that still tells the truth after Apple broke open rates. Every send is one episode of an ongoing show — design the show, not the episode. ## When NOT to use — route instead | The ask | Route to | |---|---| | One-off product launch announcement or campaign drip nurture | `../marketing/SKILL.md` | | Mail lands in spam; set up SPF / DKIM / DMARC, tracking domain, reputation | `../email-deliverability/SKILL.md` | | Write the subscribe / opt-in landing page copy | `../landing-copy/SKILL.md` | | Define the house voice, tone, and vocabulary the newsletter speaks in | `../brand-voice/SKILL.md` | | Win back / reactivate lapsed *paying customers* (lifecycle, not readers) | `../retention/SKILL.md` | | Produce the underlying long-form articles the issue links out to | `../content-engine/SKILL.md` | …

How to install
mdr add ericrisco/rsc-harness/newsletter@sha256:89d88a1f5000eb54The line at the top of this page pins the label git:20260729.bd66119, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
